Summary
Charles County amends the 2021 International Swimming Pool and Spa Code to tighten what counts as a pool barrier. Chain-link fencing must use wire at least 11.5 AWG gauge, mesh fencing is no longer an acceptable barrier at all, and a house wall can no longer rely on its windows to satisfy the 'structure wall as a barrier' option.
ISPSC Section 305.2.7, Chain link dimensions, add "wire gauge must meet or exceed 11.5" awg." ISPSC Section 305.2.4, Mesh fence as a barrier, delete without replacement. ISPSC Section 305.4, Structure wall as a barrier, delete all mentions of "windows," without replacement.
Full Breakdown
Charles County regulates pool barriers by amending, not replacing, the model International Swimming Pool and Spa Code (ISPSC) it adopted as part of the 2021 code suite under Chapter 224, Building Construction, effective with the county's May 14, 2024 building-code overhaul (Bill No. 2024-10). 9. 5 AWG, heavier than typical residential chain link. 4, Mesh fence as a barrier, is deleted without replacement, meaning mesh fencing that the base ISPSC would otherwise allow as a compliant pool barrier is no longer an acceptable option in Charles County; a pool owner must use one of the code's other approved barrier types, such as chain link meeting the new gauge rule, masonry, or ornamental fencing.
4, Structure wall as a barrier, has all mentions of 'windows' deleted without replacement, removing the ability to count a house wall's windows toward satisfying that barrier option. These are targeted subtractions from the model code's menu of acceptable barriers rather than a new standalone fence ordinance, so the remaining ISPSC Section 305 requirements, including self-closing, self-latching gates and minimum barrier height as adopted, continue to apply. Compliance is verified by the Charles County Building Code Official, the official title Chapter 224 assigns in place of 'Building Official' at § 224-1(3), during the pool construction permit and inspection process.
Violations & Fines
Chapter 224 does not set a separate fine schedule for a noncompliant pool barrier; the Building Code Official enforces ISPSC Section 305 through the pool construction permit and inspection process under § 224-1(3). A pool built with mesh fencing, undersized chain-link wire gauge, or windows counted toward a structure-wall barrier will fail inspection and cannot receive final approval until the barrier is brought into compliance with the amended ISPSC.
